Head Light
Can you replace a halogen headlight with an ordinary
headlight
It is possible to replace a halogen headlight with an
ordinary headlight, but only if the halogen headlamp is a
sealed beam. Halogen headlights with interchangeable bulbs
only accept halogen bulbs. There is a trade-off to consider;
ordinary sealed beam headlights cost less than halogen
sealed beams, but they are not as bright.
Halogen lights are about 40% brighter than conventional
incandescent lights. Light output is measured in units
called lumens, which is a more accurate measure than
candlepower. Conventional incandescent bulbs give off 15 to
18 lumens per watt. Halogens produce 20 to 25 lumens per
watt, extending average headlight range 200 feet further
down the road. Halogen light is whiter, which also aids
visibility.
The filament in a halogen bulb is thinner and burns hotter.
They are called halogen bulbs because of the gas mixture
used to fill the glass; halogen plus krypton, argon and/or
nitrogen. The gas mixture conducts heat away from the
filament to prevent it from burning out. Halogen helps
redeposit microscopic particles of tungsten that boil off
the filament back onto the filament. This extends filament
life and prevents bulb darkening with age.
